The RiD/TC module is connected to the UN200 series CPl. Afer power-on, the Sf indicator of the module is on, and the plc information displays I/0 erorrs .Is there a problem with the module?
When 200 series modules, RTD and TC modules (address range AIW) are disconnected, the PLC> message displays "I/O Module Error", "Range Out of Range Error",
This is because the module is disconnected. For RTD modules and TC modules (address range AIW), 32767 is displayed when the channel is paused, and 32000 is out of the channel range;
However, this error does not mean that the module is faulty. The module can be used normally. If all unused channels are shorted, the SF light will not be on and this error message will not exist.
